The use of a safety nut is usually required in safety-relevant applications. These are applications in lifting devices of all kinds, for example lifting platforms, vehicle lifting platforms or person lifts. However, its use is also prescribed in applications in the medical industry, for example in X-ray machines or MRIs.
Safety nuts are usually made of steel and, depending on the application, also of high-strength steels. The thread usually has a little more play than the supporting nut. In some applications, however, the catch nut is also manufactured with the same play as the main nut, in which case it must be structurally ensured that only the traveling nut takes the load.
junaspin supplies safety nuts in almost all designs, completely manufactured according to drawings. We will be happy to calculate the required nut length with you and check the strength in tensile and compression tests according to customer specifications.
